Trp63, a transcription factor related to the tumor suppressor p53, is activated by diverse stimuli and can initiate a range of cellular responses. TAp63 is the predominant Trp53 family member in primordial follicle oocytes and essential for their apoptosis triggered by DNA damage in vivo. Following γ-irradiation, induction of the pro-apoptotic BH3-only members Puma and Noxa was observed in primordial follicle oocytes from wt and Trp53−/− mice but not in those from TAp63 deficient mice. Primordial follicle oocytes from mice lacking Puma or both Puma and Noxa were protected from γ-irradiation-induced apoptosis and, remarkably, could produce healthy offspring. Hence, PUMA and NOXA are critical for DNA damage-induced, TAp63-mediated primordial follicle oocyte apoptosis. Thus, blockade of PUMA may protect fertility during cancer therapy and prevent premature menopause, improving women’s health.
